Title: Method of manufacturing a semiconductor target for a camera tube
IPC: H01L21/00
Filed: 1973-10-12
Abstract: 1447806 Semi-conductor targets; camera tubes NORTH AMERICAN PHILIPS CORP 12 Oct 1973 [16 Oct 1972] 47747/73 Headings H1D and H1K A vidicon camera tube (Fig. 1) comprises an elongate cylindrical glass envelope 1 enclosing exhausted space 6 with a light input window 5, accommodating an electron gun 7, cathode 8, control grid 9, and anode 10 surrounded by cylindrical electrode 11 connected to the anode and supporting a mesh electrode 12. A photosensitive target 14 is scanned by electron beam 13 deflected by normal electromagnetic or electrostatic means (not shown) and is clamped in the envelope between resilient rings 16, 17. The target (Fig. 2) comprises a semi-conductor wafer of, e.g. N-type Si with plural isolated P- type regions regularly arranged therein to face the electron beam, while the wafer is recessed on the opposite side to form a thin plate 30. A metal ring 19 connected to external conductor 20 is clamped between the wafer circumference and ring 17. The isolated regions 22 form rectifying junctions 23 and on scanning with electrons they are P-conducting while the substrate is N-conducting. An insulant layer 24 of, e.g. SiO 2  not in coincidence with the thickened annular region 31 contacts metal ring 19 and the surfaces of the isolated regions 22, and serves as a mask establishing P-conductive regions 22 by exposure of the substrate to a dopant, e.g. boron, to form PN junctions 23. An electron discharge layer 25 overlies layer 24 and regions 22 and consists, e.g. of cadmium telluride, antimony trisulphide, silicon monoxide or bismuth trioxide. In fabrication a preliminary layer of hafnium and tantalum nitrides are RF sputtered in argon and nitrogen on to the wafer which is thermally annealed to remove ionic, electron, and electromagnetic radiation damage during sputtering. The preliminary layer is etched off in phosphoric acid and a final electron discharge layer of, e.g. cadmium telluride is evaporation deposited on the wafer surface at subatmospheric pressures. The target is stated to have low leakage current, resistance to radiation damage, and increased signal capacity. Copper, aluminium, or silicon may be sputtered on for the preliminary layer.

Abstract: 1,113,556. Induction heating. AEG-ELOTHERM G.m.b.H. 25 Oct., 1966 [22 Dec., 1965], No. 47891/66. Heading H5H. [Also in Division F4] Induction heating equipment of the cross-field type having transversely movable plate-type conductors for accommodating workpieces of differing sizes is provided with a lifting-bar conveyer for step-by-step movement of the workpieces along the channel between the conductors wherein the lifting bar is interrupted in its rise and fall such that the worlspieces remain stationary at mid-level or at points symmetrically above and below mid-level of the conductors instead of on the floor of the channel as is usual. This ensures even heating of workpieces which differ in height from that of the conductors. The positions and durations of the stopping places are selected according to the size of the workpieces and the electrical characteristics of the equipment.

Title: Apparatus and process for production of nested plastics bags
Inventor: NESTLER RICHARD FRANKLIN
IPC: B31B19/98
Filed: 1968-10-09
Abstract: 1,247,692. Bag making. R. F. NESTLER, and D. B. MAY. 9 Oct., 1968 [9 Oct., 1967], No. 47894/68. Heading B5D. After bags have been formed from a plastics tube or folded strip a nest of bags is built up on a mandrel. In Fig. 5 mandrels 21 mounted on a wheel 21A frictionally disposed on a driven hub move in succession partly or completely into the inside of a folded strip 25 and engage a seal S 1  previously made. Another seal S 2  is made behind the mandrel to form a bag 36 which is severed from the strip. One of a second set of mandrels 38 on a chain 42 then moves inside of a mandrel 21 to receive the bag therefrom. The mandrels 38 repeatedly receive bags from the mandrels 21 so that a nest of bags are built up in each mandrel 38 with the ends of the bags being cuffed over the end of the mandrel. The strip 25 is supplied from a reel of folded strip or else means are provided to fold the strip. The strip is sealed by a heated bar, or by sound waves or light rays, and cut by a razor blade moving across the strip, or by a heated wire disposed in the heated bar. The nests of bags may be removed from mandrel 38 by air jets. Both sets of mandrels 21 and 38 may be mounted on wheels or on chains. In another embodiment the bags are formed on a hollow mandrel which has no nose piece and another mandrel which may be solid pushes each bag inside the hollow mandrel to form a nest of bags therein. The apparatus may have bars to fold the bottom edge of the strip inwardly so that bottom-gussets bags are formed. In Fig. 11 a floating mandrel 60 disposed in a plastics tube 66 has rollers to contact the inside surface of the tube and rests on rollers or on a conveyer belt. The mandrel is maintained in position by magnet 72 or by a depression in the conveyer belt. After a bag 76 has been sealed and cut by means 80, a mandrel 74 moves towards mandrel 60 (which is stationary or moves towards mandrel 74) so that the bag 76 is pushed inside mandrel 74 and mandrel 74 moves into the open end of the tube. On mandrel 74 moving back grippers on the mandrel pull the tube with it so that another bag 76 can be sealed and cut. Mandrel 74 may be one of several mandrels mounted on a turnstile so that a mandrel with a nest of bags thereon can be moved into an unloading position.

Abstract: 1445747 Digital-to-analogue conversion SIEMENS AG 19 Oct 1973 [20 Oct 1972] 48952/73 Heading H3H [Also in Division G3] The desired value of parameters for use in a control system are stored as three portion words in a digital store and are sequentially read out through a digital/analogue converter to an appropriate analogue store determined by a parameter identifying portion and part identifying portion of the word. In the system shown the parameters are the temperature, pH value and level of liquid in treatment baths 1 and each of these parameters is sensed by transducers 3 and applied as actual value signals to comparators 5, 6, 7 where they are compared with the desired value of the parameter. The value is corrected by valves 4. The desired value of each parameter for each bath is stored in digital store 10 as a binary word which includes the bath address, the nature of the parameter and the value required. An address counter 11 pulsed by generator 12 sequentially applies the words to the store output where they pass to address decoder 14 and digital/analogue converter 13. Gates 17 are operated in accordance with the address and nature of parameter information to allow the desired analogue value to be stored on a capacitor in store 9. The rate of cycling of the digital store is such that the capacitor retains the desired value substantially without error.

The complexes may be CsAsI 6 , CsI 3 , (CH 3 ) 4 NAsI 6  and (C 2 H 5 ) 4 NAsI 6  being soluble in methyl and ethyl alcohols, acetone, ethyl acetate and acetonitrile for example, the latter being removed by evacuation or flushing with a dry non-reactive gas and a gettering action being envisaged by residual impurities in the case of As containing compounds. Alternatively, a solution of a mixture of reactants producing the complex may be used. In an embodiment, vapourized As from CsAsI 6  removes residual impurities such as O 2 , H 2 O and H 2 , the former two also by Cs. In fabrication, CsAsI 6  in acetone is injected by a syringe in the envelope exhaust tube and the solvent removed through a hollow needle connected to dry nitrogen supply. Subsequently CsAsI 6  and CsI 3  liberate iodine on thermal dissociation and (CH 3 ) 4 NAsI 6  and (C 2 H 5 ) 4 NAsI 6  dissociate to hydrogen iodide for example.

This value is applied to computer 38 with "distance to go to coupling" information and the computed leaving speed is applied to retarder control 34 which releases when the speed measured by detector 42 has been reduced to the required value.
